As fiber networks expand rapidly to meet growing bandwidth demand, operators face mounting challenges—particularly in space-constrained environments like handholes, congested pits, and narrow ducts. Traditional fiber distribution methods often require bulky closures or costly civil works, slowing down deployment and increasing costs. Enter the FST Flexible Service Terminal, an innovative solution that combines compact design with plug-and-play functionality. Designed specifically for outdoor drop environments, the FST series offers hardened, pre-terminated connections with superior flexibility, reliability, and ease of installation.
In this article, we’ll dive deep into the features, benefits, and applications of the FST Flexible Service Terminal, and explain why it’s a game-changer for modern fiber rollouts.
What Is a Flexible Service Terminal?
A Flexible Service Terminal (FST) is a factory-sealed fiber distribution unit designed for tanaman luar (OSP) environments. It enables quick and reliable distribution of optical signals from feeder cables to customer drop locations in Fiber-to-the-Home (FTTH) networks.
What sets the FST apart is its compact, bendable structure and staggered-length hardened connector tails, allowing it to be easily installed in limited spaces. The FST Squid Splitter configuration offers 2 to 16 output ports in a minimal footprint, ideal for challenging installations in tight ducts, pits, or handholes.
Key Features of the FST Flexible Service Terminal
- Port Configurations: Available in 2, 4, 8, 12, and 16-port models
- Konektor yang Diperkeras: Factory-integrated, IP68-rated, and compatible with OptiTap® systems
- Flexible Design: Small branching unit with staggered tails for tight-space installation
- Pre-Terminated Assembly: Fully sealed and factory-tested to GR-326, GR-3152, and GR-3120 standards
- Splitter Options: Integrated optical splitters (1:2, 1:4, 1:8) available
- Input Interface: Hardened Multi-Fiber Optic Connector (HMFOC) with 12-fiber input
- Cable Options: Dielectric cables with nylon jackets for termite resistance
- Mounting Flexibility: Multiple mounting options for aerial, underground, or wall applications
Engineered for Harsh Environments
Itu FST Flexible Service Terminal is specifically engineered to withstand the harsh conditions of outdoor telecom deployments:
- IP68 Environmental Protection: Dustproof and waterproof to withstand moisture, mud, or flooding
- UV and Flame Resistance: TPU jacket and sealed housing protect internal components from UV exposure and extreme temperatures
- Wide Operating Range: Functions reliably between -40°C to +85°C, ensuring consistent performance in any climate
- Salt Mist and Humidity Proof: Ideal for coastal regions and high-humidity areas
Each FST is 100% optically tested to ensure minimal signal loss and maximum network reliability.
“Plug-and-Play” Installation Saves Time and Labor
One of the most significant advantages of the Terminal Layanan Fleksibel is its plug-and-play design. Traditional field splicing is time-consuming and requires skilled labor. With the FST, installation becomes fast, simple, and consistent.
- Staggered Hardened Tails: Reduce the chance of cable tangling or kinking
- Transparent Dust Caps: Easily identify ports with a visible light source
- Push-Pull Latching System: Ensures secure mating with one-step operation
- Quick Distribution Access: Distribute signal to multiple premises without additional fusion splicing
The FST simplifies network expansions and customer adds, drops, or moves with zero service disruption.

Applications of FST Flexible Service Terminal
1. FTTH (Fiber-to-the-Home)
FSTs are the ideal drop terminal for FTTH networks. They bridge the distribution point and customer premise with minimal disruption and maximum speed.
2. Micro Trenching and Handholes
In tight below-ground installations where traditional closures don’t fit, FST’s bendable design and reduced footprint excel.
3. MDUs and Urban Environments
The FST is perfect for deploying fiber in dense residential or commercial areas with limited space for infrastructure expansion.
4. Rural Networks
Pre-terminated hardened solutions minimize labor requirements, allowing service providers to quickly expand coverage with minimal technician training.
